Greg Bowyer updated SOLR-3094:
------------------------------
Attachment: SOLR-3904-Faster-NewUI-Statspage.patch
So for the initial stats page, a patch is attached that avoids enumerating the
terms for the fields. This still is a little redundant in that it brings back
the field names for the initial core stats page, but it does not incure the
large costs others have seen.
I have tested this locally, on my local index it takes about 9 seconds to bring
back the core dashboard initially, 93ms with the attached patch
I will take a look to see what can be done about the scheme browser.
> The statistics entry on the new admin UI is very slow

> Key: SOLR-3094
> URL: https://issues.apache.org/jira/browse/SOLR-3094
> Project: Solr
> Issue Type: Bug
> Components: Schema and Analysis
> Affects Versions: 4.0
> Environment: trunk only, all environments
> Reporter: Erick Erickson
> Assignee: Erick Erickson

> Prompted by Robert Reynolds (SOLR-2667), the entry point in the new Admin UI
> core drill down (e.g. clicking "singlecore" takes a long time. 28-46
> *minutes* on a 13M-23M doc set.
> On an example Wikipedia index (11M) docs, I see 21 seconds, compared to less
> than 2 seconds in the old admin UI (I'm using the old admin UI linked to from
> the new UI page on trunk). I have a very simple index layout compared to a
> commercial site. Clearly something is not right. I suspect that all the terms
> are being walked.
> This is particularly an issue because this behavior happens when I click
> "singlecore", so getting to the really neat parts of the new UI is hard.
> Robert reports on a separate thread that the same behavior happens just
> hitting admin/luke in the URL which is also slow in the 3.x world, which
> hints at where the problem lies.
> I'm going to guess that the terms are being walked and we can use the tricks
> used in SOLR-1931 to deal with the fact that admin/luke takes a long time,
> and just change the call to the entry ("singlecore") for this issue.
> Robert: Thanks for pointing this out!
